The 21st Guangzhou International Lighting Exhibition (Guangya Exhibition) was successfully held at the Pazhou Exhibition Hall in Guangzhou from June 9th to 12th. Richangjing Group (hereinafter referred to as "Richangjing") carries a number of LED filament lamp products to make a wonderful appearance, showing the corporate image and product technology of Richangjing to domestic and foreign customers.
Richang is a group company specializing in R&D, manufacturing, sales and service of LED chips and LED lighting products. As a company specializing in R&D, production and sales of filament lamps, Richangjing is committed to “building the world's largest production base for filament bulbsâ€.
It is worth mentioning that Richangjing has passed UL, CE, ROHS, FCC and other certifications, and its products are exported to 60 countries and regions such as Europe, America, Middle East and Southeast Asia. In order to achieve the improvement of production capacity, Richangjing successfully settled in the Qixingguan Economic Development Zone of Guizhou Shengbi Festival in 2015 and became the pillar enterprise of “Optical Valleyâ€.
This time, Richangjing has carried out in-depth cooperation with Guizhou Optics Valley. At present, it has been affiliated to state-owned units, and its production capacity can be greatly expanded. The slogan of “the world's largest LED filament bulb manufacturer†will also stand out.
It is understood that the production base of Richangjing Guizhou has a plant area of ​​about 30,000 square meters, with 20 LED chip back-end lines, 150 filament packaging lines, 20 finished packaging lines, and 10 finished product aging lines, which realize chip packaging to the bulb. From the molding to the assembly of the finished product, the production capacity is greatly improved, the daily production capacity is over 200,000, and the annual output value is 400 million yuan.
Liu Qiwei, chairman of the company, said: "We have produced filament lamps that can kill ordinary plastic-coated aluminum bulbs. The next step is to gradually surpass the bulb products in terms of cost performance and gradually occupy the market. â€
At the same time, at this year's Guangya Exhibition, Ri Changjing has brought a variety of filament productions to the exhibition. These include C35 tip/tail, G45/A52/A60, T45/ST/64, G80/G95/G125, A19/ST58/T30, Diamond Bubble, A52/A60/ST64, PC Bulb/Plastic Aluminum bulbs and other products.

“This year, the channel market will be mainly in China. Next, we will segment the domestic market and turn on the comprehensive market where filament lamps will break out. At the same time, we will regard product performance as the focus of future development, and continuously improve product performance and meet Customer needs." Liu Qiwei finally mentioned.
Door Bell Transformer
Doorbell transformers are typically installed at the point where the doorbell system connects to the main electrical supply. They are compact, lightweight, and designed for easy installation and maintenance. These transformers are widely used in residential, commercial, and industrial settings, where doorbells are an essential part of security and communication systems.
Key Functions
Voltage Conversion:
The primary function of a doorbell transformer is to step down the voltage from the standard household AC supply (e.g., 110V or 220V) to a lower DC or AC voltage required by the doorbell system. Common output voltages include 12V DC, 16V DC, or 10V AC.
Safety:
By converting high voltage to low voltage, doorbell transformers provide a layer of safety, reducing the risk of electrical shock or fire hazards associated with high-voltage circuits.
Compatibility:
Doorbell transformers are available in various specifications to accommodate different types of doorbell systems, including wired, wireless, and smart doorbells. This ensures compatibility with a wide range of doorbells and installation environments.
Technical Specifications
Input Voltage: The voltage range at which the transformer can accept power from the main supply.
Output Voltage: The voltage level at which the transformer supplies power to the doorbell system.
Output Current: The maximum current the transformer can deliver at the specified output voltage.
Power Rating: The total power the transformer can handle without overheating or damaging the circuit.
Size and Weight: Physical dimensions and weight, which can affect installation requirements and space constraints.
Connector Type: The type of output connector used to connect the transformer to the doorbell system (e.g., screw terminals, push-in connectors).
Installation and Maintenance
Installation: Doorbell transformers are typically installed near the electrical panel or in a convenient location close to the doorbell system. They require basic electrical wiring knowledge and follow standard electrical codes and regulations.
Maintenance: Regular maintenance involves checking the voltage output and wiring connections to ensure the transformer is functioning properly. Replacement may be necessary if the transformer fails or the doorbell system requires an upgrade.
Smart Home Integration
With the rise of smart homes, some modern doorbell systems are designed to integrate with other smart devices and home automation systems. While these systems may not require a traditional doorbell transformer due to built-in power management modules, they still rely on power conversion principles similar to those employed by traditional doorbell transformers.
Conclusion
In summary, doorbell transformers are essential components of doorbell systems, providing safe and reliable power conversion from standard household AC supplies to the lower voltages required by doorbells. Their technical specifications, ease of installation and maintenance, and compatibility with various doorbell types make them indispensable in residential, commercial, and industrial settings. As smart home technology continues to evolve, doorbell transformers may evolve alongside these systems, adapting to new power management requirements and integration capabilities.
